Abstract:

Poly(methyl methacrylate)-ZrO2(SiO2, TiO2, Al2O3) hybrid glasses have been synthesized through Sol-Gel process by using allyl acetylacetone as coupling agent. Alkoxide precursor modified with allyl acetylacetone was hydrolyzed to produce an inorganic network, and then poly(methacrylate) (PMMA) chains formed in situ through a radical polymerization were chemically bound to the forming inorganic network to synthesize a hybrid glass. Several transparent hybrid glasses have been obtained. The synthesis process was investigated by FTIR and UV spectroscopies, and the results demonstrated that acetylacetonate groups were bound to titanium(aluminium, zirconium) in the process of preparation and the final hybrid glasses, but they didn't to silicon. The results of TGA showed that the thermal stabilities of these hybrid materials were considerably improved compared with pure PMMA. Among them, the hybrid glass containing zirconia had the best thermal stability.
